Title: Projection type display device
Inventor: NINOMIYA NOBORU
IPC: G03B21/00
Filed: 1990-07-12
Abstract: PURPOSE:To obtain an oblique projection type display device which is free from the elongation of an image by adding an anamorphic optical system consisting of a couple of toric lenses or a columnar lens. CONSTITUTION:In a 3rd projection optical system 5, two toric lenses are arranged having confocal points on a yz plane and an xz plane to realize the anamorphic optical system which has a difference between (y)-directional power and (x)-directional power. When the ratio of the (y)-directional power and (x)- directional power of the 3rd projection optical system 5 is set to the reciprocal of the ratio of the (y)-directional power and (x)-directional power of an image by a 1st projection lens 2 and a 2nd projection lens 4, the elongation of the image on a screen 6 can be corrected by the 3rd projection optical system. Namely, a square image on a light valve 1 is formed having trapezoid distortion through the 1st projection lens 2 and the image having the trapezoid distortion is formed through the 2nd projection lens 4 on the screen as an image having no trapezoid distortion, thereby correcting the elongation of the projection image on the screen by the 3rd projection optical system 5 which is the anamorphic optical system consisting of at least the couple of toric lenses.

Title: Tuner
Inventor: NAGAI JIYOUJI
IPC: H03B21/02
Filed: 1980-12-25
Abstract: PURPOSE: To cover the entire channel band and to exclude the interference of adjacent channels, by the frequency conversion of a sum or difference signal from the 1st and 2nd local oscillator and making further frequency conversion at one of a local oscillator.  
     CONSTITUTION: A high frequency signal from a terminal 1 is amplified at a high frequency amplifier 2 and applied to the 1st mixer 5. A sum or difference signal between the 1st and 2nd local oscillators 4, 9 is produced at a frequency mixer 30 and it is applied to the 1st mixer 5. The 1st intermediate signal frequency- converted is amplified at the 1st intermediate frequency amplifier 7. The 2nd intermediate frequency signal is formed at the 2nd mixer 10 by a signal from the 2nd local oscillator 9 and the 1st intermediate frequency signal. Thus, since the local oscillation frequency range is determined with a capacitance ratio of varactor diodes, the frequency range can be taken wider at the same capacitance cange and the interference at the adjacent channel can be excluded.

Abstract: PURPOSE:To eliminate increase of a cost, frequent generation of a trouble, enlargement of a size, increase of a noise, etc., with a constitution simplified, by forming a conveying drive system associated with a route switching mechanism, and performing branching by only conveying power control. CONSTITUTION:When paper sheets are fed out to branch downward, when a drive pulley 5 is rotated in the clockwise direction by a drive motor 10, a planet gear 17, meshed with an internal tooth gear 18 in the drive pulley 5, is rotated around while rotated on its own axis. In this way, a switching actuator l is moved to a position where its stopper receiving part 20 is brought into contact with a chassis stopper 19. As a result, the paper sheet is guided by the switching actuator 1 to flow downward and conveyed by a belt 9. On the other hand, when the paper sheet is fed out to branch in a lateral direction, by rotating the drive pulley 5 in the counterclockwise direction to move the position of the switching actuator 1, the paper sheet is transfer fed in a lateral direction and conveyed by the belt 9.

Title: Echo canceller
Inventor: KUGIMIYA JUNICHI
IPC: H04B3/23
Filed: 1989-07-18
Abstract: PURPOSE:To stably perform the update control of data in a memory by stopping the update of the data in the memory for coarse adjustment when it is judged that a residual signal exists between a pair of levels. CONSTITUTION:When an Update quantity control circuit 4 further compares the residual signal ECER with a pair of judging levels for positive/negative and it is judged that the residual signal exists between the pair of levels, the update of the data is stopped setting a correction quantity for the output data of the memory 2 for coarse adjustment at zero. In other words, by using not only the judging level '0' used in the update quantity control circuit 4 but the judging level consisting of two judging levels (a) and (b) (a>0>b) interposing '0', the update quantity from the update quantity control circuit 4 for the memory 2 for coarse adjustment goes to zero when the level of the residual signal ECER exists between the pair of judging levels, and the update of the memory 2 for coarse adjustment is stopped. In such a way, it is possible to eliminate the fluctuation of echo replica generated so as to block the update of internal data in the memory 2 for coarse adjustment when the residual signal ECER is set at a low level so as to be within the pair of judging levels.

Title: Plasma processor
Inventor: SUZUKI KAZUO
IPC: H01L21/302
Filed: 1988-07-27
Abstract: PURPOSE:To make both uniform large diameter plasma production and uniform processing of large diameter specimens feasible by a method wherein the diameter of a discharge tube at the incident end of microwaves is specified to be around the minimum diameter of a waveguide, forming a microwave incident window, while a vacuum chamber taking a horn type antenna shape is provided in the direction from the incident window to specimen. CONSTITUTION:The diameter of a discharge tube 2 is specified to be around the minimum diameter of a waveguide while a specimen chamber 5 is to take a conical horn type antenna shape in the direction from the connecting part with the discharge tube 2 to a specimen 5. Consequently, microwaves 11 can be propagated efficiently in the direction to the specimen 5 without changing the mode of microwaves 11. Besides, a magnetic field coil 10 in diameter larger than the diameter phiD of the specimen 5 can be notably miniaturized by overlapping with the magnetic field afforded by smaller magnetic field coil 3 in diameter almost equal to that phid of the discharge tube 2. The intersecting diameter of the surface 13 in ECR magnetic flux density with that of the metallic specimen chamber 4 is to be phiD so that, if the mode of microwaves 11 reaching this diameter phiD is kept uniform, uniform plasma may be produced within the range in this diameter phiD resultantly enabling uniform plasma processing to be performed within the range in this diameter phiD' even if the diameter phid of the discharge tube is smaller than the diameter phiD of the specimen 5.

Title: Magnetic information recorder
Inventor: HIBINO HIDEOMI
IPC: G11B5/09
Filed: 1994-08-08
Abstract: PURPOSE:To magnetically record all information on a film even when temperature becomes abnormal. CONSTITUTION:This recorder is applied for a magnetic recorder provided with an IC6 for driving a head. When the temperature in the IC6 becomes equal to or over a first reference temperature, the level of a signal line TS is made low by a temperature detection circuit in the IC6. When the level of the signal line TS becomes low, the level of a signal line PC is made low by a CPU3 and the level of a signal line VE is made low by a power source 11 in the IC6. Thus, a voltage is stopped being supplied to a head driving circuit 12 and a current does not flow to a magnetic head 7. That is to say, when the abnormal temperature is detected, a PPM signal is stopped being transmitted from the CPU3 and the action of the IC6 is stopped by the temperature detection circuit. When the temperature becomes equal to or under the second reference temperature being lower than the first reference temperature thereafter, the current flows to the head 7 again.

Filed: 1982-10-25
Abstract: PURPOSE:To prevent seizure of a pump or damage of a link by installing a handle shaft revolution detecting part consisting of a luminous element and a light receiving element onto a reduction shaft interlocked with a handle shaft and operating a solenoid valve by the output signal of said detection part and controlling the flow of pressurized liquid. CONSTITUTION:A transmitting and shielding member 7 is installed onto a reduction shaft 6 interlocked with the revolution of a handle shaft 1. A luminous diode 8 and a phototransistor 9 are arranged at the opposite positions each other, having the transmitting and shielding member 7 interposed. Said transmitting and shielding member 7 transmits light only at the limit steering angle of a handle. Said phototransistor 9 is connected to a solenoid valve set onto a piping interposed between an oil tank and a power cylinder. Therefore, when the handle is turned by the limit steering angle, the phototransistor 9 operates to switch the solenoid valve 10. Therefore, the working-oil feed side of the power cylinder communicates to the oil tank, and the pressure is reduced sharply, so excessive force is not applied onto a pump 5 and a link mechanism.

Filed: 1994-07-18
Abstract: PURPOSE: To form a Bragg diffraction grating on an optical fiber or the like by irradiating an optical transmission body with chemical rays polarized for more than a specified ratio in a polarization direction parallel to a plane including a propagation axis at the time of irradiating the optical transmission body provided with an optical propagation axis with the chemical rays. CONSTITUTION: In this method for selectively changing the refractive index of the transmission body, at the time of irradiating the optical transmission body 20 provided with the optical propagation axis with the polarized chemical rays, it is irradiated with the chemical rays polarized for at least 60% in the polarization direction parallel to the plane including the propagation axis. In this case, radiation polarized for 60% is the radiation of the chemical rays for which the 60% of radiation intensity is transmitted by a polarizing filter placed along one axis. Thus, chemical ray irradiation with an interference pattern is formed first, the transmission body 20 is exposed to the interference pattern and the Bragg diffraction grating 10 is formed in the transmission body 20. Thus, even by the chemical ray irradiation with the polarization of the low level of about 60%, an article provided with the refractive index disturbance pattern of the Bragg diffraction grating or the like isotropic to the optical fiber or the like is formed.

Title: Fire detector with ratio detector for infrared ray and ultraviolet ray
Inventor: ROJIYAA EE UENDO
IPC: G08B17/12
Filed: 1982-10-26
Abstract: An automatic fire detection system characterized by an extremely low incidence of false alarms utilizes two detection channels, one fed by an infrared (IR) detector and the other by an ultraviolet (UV) detector. Signal processing electronics in each channel produce a normalized output signal proportional to the power of incident IR and UV radiation within specific bandwidths. The system features a ratio detector that repeatedly forms a ratio of the normalized IR and UV inputs and compares the ratio to a known range of values for this ratio that are characteristic of a fire. A discriminator connected to the output of the ratio detector generates a fire alarm signal only if the majority of these ratio comparisons are fire-indicating. The system also includes a feedback loop in the IR processing channel that automatically adjusts the output of the channel to compensate for time-verying background IR radiation such as sunlight.

Filed: 1981-11-24
Abstract: PURPOSE:To attain the variable attenuation while keeping a constant impedance, by controlling a current flowed to a series circuit consisting of diodes and resistors provided at input and output terminals of a 1/4 wavelength transmission line. CONSTITUTION:An output signal from a signal source 2 is transmitted to a 1/4 wavelength transmission line 10 via a coupling capacitor C1 and outputted from a terminal 5 via a coupling capacitor C2. In applying a DC control voltage to a terminal 6, a current flows to diodes D1, D2. The high frequency resistance of the diodes is changed depending on the current value. Thus, the attenuation of a signal transmitted from the signal source 2 can be changed. The resistance value of resistors R1, R2 connected in series with the diodes D1, D2 is made equal to the characteristic impedance of the line 10, allowing to make the impedance viewed from the terminal 5 constant.
